Thisrwill" prevent the foundations engine crank shaft, clutch parts and other 1 parts of the transmission and engine.

of engine and transmission from becomingfloo'se. 'andjwill remove strain from the bearings and'thus prevent breaking'of the It will also permit a smaller engine house to be used and will simplify the installation and the operation of the power unit. a

a I Another object of the invention is to connect one end of the crank shaft of the engine directly with the pulley shaft and to connect the other end of the crank shaft with a reversing shaft which is geared to the pulley shaft, with clutch means-for per mitting'the pulley shaft to be driven from claim.

ieither connection.

=Th1s inventionalso consists in certain other features of construction and in the combination and arrangement ofthe several parts, to be hereinafter fully described,

illustrated in the accompanying drawings and specifically pointed out in the appended In describing my invention in detail, reference will be had to the accompanying drawings, wherein like characters denote like crank shaft.

or correspondingparts throughout the sev- GREI-l VIGWS, and in Wh1ch:-

Figure 1 is a plan view of the invention.

Figure 2 is an end view.

Figure 3 is a horizontal sectional view through the transmissionmeans.

As shown in these views, the transmission means are arranged in front of the engine,

instead of at the side thereof, as is usual, so that vthe strain is'al direct one and not a side strain as is the case where. thetran s-i mission is connected with-one end of the By front end, I mean the crankshaft end of the bed plate.

In carrying out my inventionfI connect the frame 1 of the transmission B to the end course, be understood that the frames may be formed integral or connected together in any desired manner'and may be supported by any suitable kind of a base. A sprocket 5 is connected to each end of the crank shaft of theengine', the connecting rod'l ofthe 2 piston of the engine being connected with,

the center oft-he crank shaft, as shown;]

fSprock'et chains 8] and 9 pass over the 's prockets 5 and-the chain 8- passes overa sprocket 10-wl1ich is formed witha .clutc'h part 11 and is loosely mounted on "a'shaft '12 which is rotatably mounted in the frame "'1 and to which-the pulley 13 of the transf missionmeansiis' secured. The chain 9 passes over a" sprocket 14 which has a clutch part 15 and which is loosely mounted on a shaft journaled in the'frame 1 and :to, which is keyed a gear 17 which meshes with a gear 18 keyed to the shaft 12. A clutch part19 engages the part 11 and is keyed to shaft 12,

so that it can slide thereon, and a clutch part 21 engages the part15 and is slidably mount-M ed on the shaft 16 but is caused to rotate withsaid shaft by means of a key. The keys are shown at 22. v i v A clutch leveris pivoted to an extension 23 oneach post 1 of the frame 1. Each lever has its forked upper end engaging a groove in each movable ormale part of each clutch'assembly and the lower-ends of the levers engage grooved collars 24 which are carried by arod 25 slidabl-y mounted in the post 1. A collar 26 is" connected with one so I end ofsaid rod 25, and theforkedendof the bell crank 27 engages said collar 26. A link 28 connects the bell crank with a hand lever or othermanua'lly operated. part, so

in front of the crankshaft of'the engine and it will be seen that I are connected therewith by the chains 8 and I 9. Itwill also be seen that when thehand lever or otherpart to which the link 28 is attached is shifted. in one direction, the clutch part 19 will engage the part 11 through the shifting of the rod:20, While the part 21 ismoved out of engagement with the.

part 15. This will cause the shaft 12 and v A pulley 13 to be rotated directly fromthe crankshaft through means of the chain 8' and the sprockets 5 andv 10. When the hand 21 will engage thepart 15, so that the drive will be from the crank shaft, sprocket 5,

chain 9, sprocket 1 1 to shaft 16 and through .lever is shift-ed in an opposite direction, "the part 19 will leave the part 11; and the part.

the gears 17 and 18 to the shaft 12, so that the pulley 13 will be driven in a reverse direction. When the lever is in a neutral position, both male parts ofthe-clutchwillbe out of engagement With the female part.

The main purpose of this inventionis to place the transmission in front of the engine to secure a straight line pull" instead of an angular one. The invention is mainly intended for use on horizontal engines used in the oil fields though it will, of course, be understood that it is applicable to other engines and for different purposes.

Itis thought from the foregoingdescription that the advantages and novel features of myinventionywill be readily apparent.

Iflde'sir'e it to be understood that I'may make changes in the construction and in the combination and arrangement of the several shaft and a base upon Which the crank shaft H is journaled, a second base connected with the front end of the first base, a pair of shafts journaled in-the second base, gears 1 connecting the two shafts together, sprocket means connecting each shaftWith the crank shaft, a pulley on one shaft, clutch means for connecting each sprocket means vvlth each shaft, a rod slidably mounted at the front of the second base, means for sliding the rod, a pair of grooved collars on the rod, a lever for shifting each clutch means, one end of each lever engag ng one of the collars.

In testimony whereof I aflix mysignature. LUTHER E. SCAGGS.
